TL Item#: 107417 Category: Mold Making & Casting

Poly 1512 Liquid Plastic is a two-part, liquid polyurethane resin that cures (RTV) to a white, Shore D71 plastic. This product has a simple 1A:1B mix ratio by weight. When cured, it has the feel and density of hard wood or thermoplastics. Poly 1512 is a pourable plastic, but it can be easily thickened with PolyFiber II Thickener for brush-on application. For a faster-setting version, consider Poly 1512X Liquid Plastic.
